My mother is an artist. She told me a long time ago that she paints because that is what she finds joy in doing. She has never made a lot of fame or fortune through painting. Nor are you likely to see any of her work hanging at a fancy museum anytime soon, but she does it anyways. I think she has given me a great example when it comes to choosing a profession. Teaching is unlikely to ever make me the kind of money that I could make in other professions, and it is unlikely I will be known throughout the world for my scholarship. I am pursuing this career anyways because it is what brings me joy.
Not only do I get so much out of working with students, and writing and learning myself, but I think that I can give a lot more to the students if I do so with joy in my heart. Whenever I have taught a lesson about something that really interest me, I find that my students become more interested in the subject. This is unlikely because our interest match up so precisely, I think it is much more likely caused by them responding to my attitude and energy. So I will endeavor to do whatever it is I am doing with joy.
